Disable automatic shader compilation on thumbnail generation

Anytime you right click on a highlighted asset in the content browser, UE will start to compile shaders for that asset if they haven’t already been compiled. This is especially noticeable when right clicking on maps. Even if you want to delete the assets you often have to wait for the shaders to finish compiling before you can delete them.

I think this happens when generating the thumbnail for the asset. But, there are many times when I’m editing or moving assets and I don’t have time to wait for 10,000 shaders to compile just so a few thumbnails can be generated. Especially if I’m right clicking on those assets only to delete them, compiling the shaders in that case is a complete waste of time. I often end up having to kill the shader compiler in task manager, because the editor seems to lock up during compilation.

Is there anyway to prevent shaders from compiling automatically on thumbnail generation?
